Re: STM32L432 Nucleo 32 board

I've just tried it with 3 x 1.5v batteries connected to +5V (CN4-4) and had the same problem. My multimeter read 4.85 volts which should be OK.

I also tried with a 9V battery connected to VIN (CN4-1) and that worked as expected. When it does work the ST_Link LED also flashes red.

Re: declarations and scope rules

Your original quote omits some crucial information which totally changes its meaning: The scope extends textually from the point of the declaration to the end of the block (procedure or module) to which the declaration belongs and hence to which the object is local. Your expectations of the Language...

Re: declarations and scope rules

I apologise for the the delay in approving your first post. Any subsequent posts of yours will be accepted immediately. You can reuse identifiers in nested procedures. However, unlike Pascal and Modula-2, you can only access 'strictly local' or global identifiers from within a nested procedure. Hope...

Re: HCFiler compiling problems

Refer to the system requirements for HCFiler in the ReadMe.htm file. i.e. you need to use v6.2 of Astrobe to compile the source code as it uses some of the new features summarised in What's New in Astrobe for Cortex-M3 . The problem where additional (superfluous) bars were not allowed before the fir...
